COTTON-PICKER.

SPECIFICATION forming part of Letters Patent No. 347,382, dated August 17, 1886.

Application filed July 1, 1895. Serial No. 170,389. (No model.) Patented in Germany July 15,1884, No. 31,439; in France November 3, 1884. No. 165,149, and in England November 5, 1884, No. 14,640.

.To @ZZ whom,v it may concern.-

Be it known that I, GEORGE RrsLER, a citi zen of Germany, residing at Sennheim,Alsace, in the German Empire, have invented certain new and useful Improvements in Cotton-Pickers, of which the following is a specification.

My invention relates to machines for preparing cotton for carding, and consists of an improved picker, with a Aset of three revolving drumsprovided with card-clothing and being partially surrounded with grating. The manner in which the cotton is acteda upon resembles very much the process of carding, and a lap is obtained therefrom in which the fibers u are laid very nearly parallehand are freed from knots, leaves, and seeds. By thisprocess the necessary succeeding operation is greatly facilitated. I `obtained a United- States Patent No. 234,613, November 16, 18.80, for a picker very similar to the one presented in this specification, but having only two drums. It had the defect to clean the bottom face of the deliverylap not quite as well as the top face of said lap, because only one dofng-cyliader was combined with the main cylinder.

The object of my invention is to overcome this defect and to clean the lap equally throughout. rlhis result is obtained by adding a second dofng-cylinder, at the same time also increasing the grate surface.

Figure l of the accompanying drawings represents a vertical section of the machine. Fig. 2 represents an outline of part of the machine, in which is shown the driving mechanism. Fig. 3 represents a detail view of. the hinged cover beneath the grates.

The drawings show in Fig. l a longitudinal section of the picker. As there are many parts in my machine which are found in most all pickers or lappers, and which are therefore well known to those skilled in the art of cotton spinning, I shall not describe said parts with more minuteness than is necessary, but shall simply refer to machines well known in the trade. A y

f f designate the framing of the picker, sustaining the operating parts of the device.

A represent-s a cylinder of cast-iron or wood covered with strong card-clothing, saw-blades or wooden laggins with steel points, such as are also used in other pickers, and have been illustrated in my Patent No. 234,613, Fig. 3. This clothing of cylinder A with regard to size, number, and inclination of teeth, has to be selected according to quality of cotton.

B and C are other cylinders of cast-iron or wood,and are covered with similar card clothing, as cylinder A. Cylinder B is located underneath cylinder A and cylinder C, beside cylinder B. The surfaces of said drums set at the same distance from each other as the doffers,and likewise are set from the card or main cylinder in ordinary cards.

g is a grating,which lies about the arc of the revolution of cylinder A, which is between the feeder and the cylinder B. Grating g partially surrounds cylinder B, and gratinggl partially surrounds cylinder C, and g3 is a grating located between cylinder C and the dust-cages D L.

E designates a feed-roller revolving within a shell marked with F, and the cotton passes between this roller and over said shell on its way from the feeder to cylinder A. The feeding device is marked with a a, and consists of an apron onto which the cotton is putin shape of lap-rolls, as it is usual in lappers and pickers. Partition sheets of wrought-iron t" and i2 are secured to the framing f underneath the grating gand g', and' sheets i', it, and t3 inclose a certain space beneath said grates for the reception of the seeds,.leaves, and other impurities, which are thrown out through the gratebars owing to the centrifugal force imparted to these impuritieslby the revolving cylinders. Beneath the sheett's a horizontal fine or trunk is formed by the floor, bysaid sheet i and by the lower portion of the framings f of the machine. A vertical due is formed between sheet i and a sheet, i5, which runs up Vfrom the floor to grate g2.

D D are screen-cylinders or dust-cages, which are in communication by means of a flue to the fan N, and are combined with the lapping apparatus M in the usual manner, as shown also in my Patent No. 234,613. Between said dust-cages and between the grate g2 a fourth grating, g3, is arranged, the bars of which run longitudinally with regard to the machine, while the bars of grates g, g', and gt' ECO run crosswise. The gratcs g3 and y? are shut off air-tightly by means of covers c, hinged underneath the same, in order to prevent the current of air from passing through said grates.

The cotton,which is fed on the apron,is conveyed to the cylinder A by the feed-roller in shell E and F, and will be opened rst by the cylinder A, after which it will be delivered to the doffing-roller B, and will be still more opened by the same. This roller B will conrey the cotton to the doffer C, whereupon the cotton will be caught by the draft or current of air which is created by the fan, and which carries the cotton up toward the dust-cages. There said cotton is condensed and formed into a sheet or lap. The suction produced by fan N will act through the usual iine and the usual dust-cages, and will create a current of air which enters the machine at Z and, flowing through the iiuc underneath sheet is, and through the ilue between sheets i2 and t5, will pass between cylinder C and grate qu up toward the cages. The cotton therefore, while being` dragged along by the cylinders A, B, and C over the respective grates (1 andy', will be carried by the said current of air over grates g2 and g", and will drop most of the impurities mixed therewith through grates g and y," and into the grateboxcs It and if.

The cleaning of the drums A, B, and Gis always assured from the peculiar construction and arrangement ot' the teeth thcreon,and by the surrounding grating, which relieves them by allowing the impurities to pass off. The

` bars in the gratings y and g2 may be placed at diiierent distances apart and at different inclinations relative to the revolution of the drums. I prefer to drive the cylinder A at a speed of nine hundred to one thousand revolutions per minute, and the cylinders B and C at a speed of six hundred and fifty to seven hundred and twenty revolutions per minute, in order to secure the most efficient action and the best result.

In Fig. 2 is represented a series .of pulleys and belts of which K is the driving-pulley, connected by means of the belt 10 with the pulley L mounted on the aft L', carrying the toothed cylinderA and pulley L2, the latter of which is connected by means of a belt, 1l, with one of the two pulleys L3 mounted on the shaft L4 carrying the small toothed cylinder B. One of the pulleys L3,of which there is but one shown, is also connected by means of the belt l2 with pulley L, which is mounted on the shaft L5 carrying toothed cylinders C and pulley L", which is connected by means of belt 13 with pulley L7 mounted on the shaft LE carrying the perforated cylinder'r D and the pulley L", which is connected by means of the belt 14 with pulley Lw mounted on the shaft Lu carrying thc small perforated cylinder 1) and pulley L, which is also connected by means of the belt l5 with pulley Ll mounted on the shaft carrying the fau h.

Vhat Il claim is- The combination, substantially as shown iVitnesses:
